Device for Holding Timing Gears

Abstract

Disclosed is a device for holding a relative angle between two timing gears. The device includes a connector, two stationary engagement elements, two levers, two movable engagement elements and two fastening units. Each of the stationary engagement elements extends from the connector and can be located between two adjacent teeth of a related one of the timing gears. The levers are pivotally connected to the connector. Each of the movable engagement elements is movably connected to a related one of the levers and can be located between two other adjacent teeth of a related one of the timing gears. Each of the fastening units is operable to retain a related one of the movable engagement units in position relative to a related one of the levers.

Description

BACKGROUND OF INVENTION[0001]1. Field of Invention[0002]The present invention relates to a vehicle and, more particularly, to a timing belt wound around timing gears of a vehicle and, more particularly, to a device for holding timing gears of a vehicle when a timing belt is disengaged from them.[0003]2. Related Prior Art[0004]A vehicle includes a timing belt wound around timing gears to drive cam shafts and a crank shaft to open and close valves of cylinders in a predetermined order. The timing belt is made of rubber that suffers fractures due to aging, excessive stress, erosion for example. The timing belt must be checked and replaced with a new one regularly to ensure normal operation of the vehicle.[0005]To replace an old timing belt with a new timing belt, the relative angle between the timing gears must be retained to ensure precise timing of the opening and closing of the valves. If there is any error in the relative angle between the timing gears, the power of the engine will...

AI Technical Summary

Benefits of technology

[0010]It is the primary objective of the present invention to provide a reliable device for holding a relative angle between timing gears.

Problems solved by technology

If there is any error in the relative angle between the timing gears, the power of the engine will be jeopardized.

If the error is serious, it could damage the engine and / or other elements related to the transmission of power.

Human memory is however not reliable, and the correct relative angle between the timing gears is not ensured.

Hence, the new timing belt around the timing gears is always driven manually for several rounds before the engine is started, and this is an inconvenient practice.
